Fuel Cooling - All Others: Notes
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2019 Ford Transit-350 HD, 2019 Ford Transit-350, 2019 Ford Transit-250, 2019 Ford Transit-150, and 2019 Ford F-550 Super Duty.

Fuel cooling is required to maintain an acceptable fuel temperature during engine operation. The fuel system temperature is monitored by the fuel pressure and temperature sensor, which is an input to the PCM. The powertrain secondary cooling system cools the fuel cooler, in addition to cooling several other auxiliary engine systems. The coolant flows from the fuel cooler to the powertrain secondary cooling system coolant pump to the powertrain secondary cooling system radiator back to the fuel cooler.
